Currently, link between "elements" are represented in the model (jasminemodel.ecore) as object (extending IConnector) containing a reference to a source and a target. And when user create a link between 2 elements, a Connector is created but there's no reference of it in source object or in target object (kind of Type based links described in http://wiki.eclipse.org/index.php/GMF_Links).

In my opinion, a better approach should be a reference based link approach describe in previous document. Using the GMF Opposite mechanism when model needs cross-references.
